For the sake of understanding the present embodiment, first, an application scenario of a cargo loading system disclosed in the present embodiment is described, and referring to fig. 1, which is a schematic diagram of an application scenario of a cargo loading system provided in the present embodiment, including a workstation 10, a control server 11, a handling device 12, an automatic loading device 13, a cargo conveying device 14, at least one cargo loading position 15, a movable carrier queuing position 16, a carrier storage area 17, a cargo to be loaded 18, and a plurality of movable carriers 19, where the plurality of movable carriers 19 are stored in the carrier storage area 17, and a preferred movable carrier 191 is included in the movable carriers 19. The workstation 10 is provided with an automatic racking device 13, a cargo conveyor 14, a cargo racking station 15, a movable carrier queuing station 16, and a shipment station 20.

In the process of being applied to the scenario of loading cargoes, the control server 11 may implement scheduling of the handling device 12 and the automatic loading device 13, may utilize the handling device 12 to handle the preferred movable carrier 191 in the carrier storage area 17, may utilize the cargo conveying device 14 to convey the cargoes 18 to be loaded to the unloading space 20, and may utilize the automatic loading device 13 to implement the loading process of the cargoes 18 to be loaded.

For example, the control server first dispatches the handling device to handle the preferred movable carrier to the movable carrier queuing position near the workstation for queuing, dispatches the handling device to handle the preferred movable carrier to the cargo loading position after the cargo conveying device conveys the cargo to be loaded to the cargo unloading position and the control server receives the loading demand, and dispatches the automatic loading device to place the cargo to be loaded on the cargo loading position into the preferred movable carrier positioned on the cargo loading position.

Exemplary, the movable carrier may include, but is not limited to: movable carriers (baffle shelves, container shelves, etc.), pallet supports, cage carts, pallet supports, etc. The handling device may be a handling robot, such as an automated guided vehicle (Automated Guided Vehicle, AGV) or the like. The automatic loading device can be a mechanical arm, such as a six-axis mechanical arm.

A cargo racking system provided in accordance with an embodiment of the present disclosure is described below, the system comprising at least one control server 11, at least one handling device 12, a carrier storage area 17 storing a plurality of movable carriers 19, at least one workstation 10, and at least one automated racking device 13; the movable carrier 19 is provided with a plurality of goods shelves for storing goods to be shelved, any one of the at least one workstation is provided with at least one automatic racking device, at least one movable carrier queuing position and at least one goods shelves; wherein the at least one control server is in wireless communication with the at least one handling device and the at least one automated racking device, respectively.

Reference is now made to fig. 2, which is a schematic diagram of a system for loading cargoes, in which the control server 11 respectively dispatches the handling device 12 and the automatic loading device 13 to complete loading and storage of cargoes to be loaded. Wherein:

the control server 11 is configured to screen at least one preferred mobile carrier from the carrier storage area and schedule the at least one handling device to handle the at least one preferred mobile carrier to at least one empty mobile carrier queuing position at the workstation based at least in part on the racking requirement information for the goods to be racking and the current empty carrier location information for each mobile carrier before assigning the racking tasks to the workstation, schedule the at least one handling device to handle the at least one preferred mobile carrier from the corresponding mobile carrier queuing position to the at least one goods racking position after assigning the racking tasks to the workstation, and schedule the at least one automated racking device at the workstation to place the goods to be racking at the workstation to the preferred mobile carrier at the at least one goods racking position.

Here, the control server may store in advance the racking requirement information of each of the to-be-racking goods to be put on the goods conveying device, wherein the racking requirement information includes storage goods location information of the to-be-racking goods to be racking, for example, taking the movable carrier having five layers of goods locations as an example, the racking requirement information of the to-be-racking goods a is a third layer of goods location stored on the movable carrier, the racking requirement information of the to-be-racking goods B is a first layer of goods location stored on the movable carrier, and the racking requirement information of the to-be-racking goods C is a mixed storage goods location stored on the movable carrier storing the goods D.

For example, the pre-storage may be stored before the goods to be shelved are put into the goods conveying device. The handling device 12 is configured to handle at least one preferably movable carrier to at least one empty movable carrier queuing position at the workstation; at least one preferably mobile carrier is transported from the respective mobile carrier queuing position to at least one on-load rack position.

Here, the handling device is in wireless communication with the control server, and when receiving the scheduling instruction sent by the control server, the handling device can handle the preferred movable carrier from the carrier storage area to at least one empty movable carrier queuing position of the workstation based on the position of the preferred movable carrier in the carrier storage area carried by the scheduling instruction; the preferred movable carriers can also be transported from the corresponding movable carrier queuing positions to the cargo upper rack positions based on the positions of the cargo upper rack positions carried by the scheduling instructions.

The automatic racking device 13 is configured to put goods to be racking at the workstation on a preferably movable carrier at the at least one goods racking location.

Here, the automatic loading device is in wireless communication with the control server, and under the condition that the dispatching instruction sent by the control server is received, the goods to be loaded on the workstation can be placed on the preferential movable carrier on the goods loading position based on the preferential movable carrier carried by the dispatching instruction on the position of the goods loading position.

For the current empty space information of each movable carrier, specifically, the current empty space information may include position information of a current empty space of the movable carrier, further, whether the movable carrier is an empty movable carrier may be detected according to the current empty space information, for example, it may be determined that each storage space of the current movable carrier is empty according to the current empty space information, and then it may be determined that the movable carrier is an empty movable carrier; in the case where the movable carrier is at least partially stored in the non-empty storage space, it may be determined that the movable carrier is a non-empty movable carrier.

Alternatively, the number of empty spaces of the movable carrier may be determined according to the current empty space information, the type of each empty space, etc., and the number of empty spaces may be calculated, for example, according to the position indicated by the position information of the empty space. Here, the type of the empty cargo space may include a type of a layer cargo space of the movable carrier, such as a first layer cargo space, a second layer cargo space, … …, an nth layer cargo space, N being a positive integer.

Here, the non-empty mobile carrier may include a mobile carrier without an empty cargo space and a mobile carrier with a partial empty cargo space; wherein the non-empty mobile carrier may comprise a hybrid storage cargo space; the hybrid storage cargo space is used for storing at least one SKU to be put on shelf.

In one possible implementation manner, after determining that the movable carrier in the carrier storage area does not have empty cargo space, it may further determine whether the non-empty cargo space in the movable carrier belongs to the mixed storage cargo space according to information of the cargo stored in each storage cargo space in the movable carrier. In the case of determining the mixed storage cargo space where the cargo C and the cargo D are present, the movable carrier where the mixed storage cargo space is present may be determined to be a preferable movable carrier in the case of determining that the cargo C to be put on is to be mixed stored with the cargo D according to the put on demand information of the respective cargoes to be put on.

In a possible implementation manner, the control server is further configured to determine, based on the racking requirement information of each of the cargoes to be shelved, a storage cargo space of each of the cargoes to be shelved and a type of each of the storage cargo spaces; and determining the duty ratio information of each type of storage cargo space in all storage cargo spaces, and screening at least one preferable movable carrier from the carrier storage area based on the duty ratio information and the current empty cargo space information of each movable carrier. The types of storage locations include the tier types of the movable carrier, such as a first tier, a second tier, … …, and an nth tier, where N is a positive integer.

In a specific implementation, based on the above-mentioned information of the loading requirements of each cargo to be loaded and the current empty space information of each movable carrier, at least one preferable movable carrier with a high probability of meeting the loading conditions of the cargo to be loaded can be screened out from the carrier storage area, and at least one transporting device is scheduled to transport the at least one preferable movable carrier to at least one empty movable carrier queuing space located at the workstation. For example, taking a movable carrier with five layers of cargo positions as an example, from bottom to top, a first layer of cargo position (bottom layer cargo position, i.e. non-gold cargo position), a second layer of cargo position (gold cargo position), a third layer of cargo position (gold cargo position), a fourth layer of cargo position (gold cargo position), a fifth layer of cargo position (top layer cargo position, i.e. non-gold cargo position), according to the loading demand information of each cargo to be loaded, it is determined that 50% of cargo to be loaded is to be stored in the third layer of cargo position, it is determined that 20% of cargo to be loaded is to be stored in the second layer of cargo position, it is determined that 15% of cargo to be loaded is to be stored in the fourth layer of cargo position, it is determined that 5% of cargo to be loaded is to be stored in the first layer of cargo position and the fifth layer of cargo position, and it is determined that 5% of cargo to be loaded is to be stored in the mixed storage cargo position. In one case, a movable carrier that mostly satisfies the condition that the third layer of cargo space is empty may be selected as a preferable movable carrier in the carrier storage area according to the current empty cargo space information of each movable carrier, then a movable carrier that mostly satisfies the condition that the second layer of cargo space and the fourth layer of cargo space are empty may be selected as a preferable movable carrier in the carrier storage area, a small number of movable carriers that the first layer of cargo space is empty and the fifth layer of cargo space is empty may be appropriately selected as a preferable movable carrier, and finally a movable carrier that satisfies the mixed storage cargo space is selected as a preferable movable carrier. At least one handling device may then be scheduled to handle the selected at least one preferred mobile carrier to at least one empty mobile carrier queuing station located at the workstation.

In the case of a limited number of queuing positions of the movable carriers, the handling device may be further sequentially scheduled to handle the above-mentioned preferred movable carriers according to a priority order, for example, to handle the preferred movable carrier of the empty third-layer cargo space first, to handle the preferred movable carrier of the empty second-layer cargo space second, to handle the preferred movable carrier of the empty fourth-layer cargo space, to handle the preferred movable carrier of the empty first-layer cargo space second, or to handle the preferred movable carrier of the empty fifth-layer cargo space. Alternatively, the plurality of handling devices are dispatched at a time to handle a portion of the empty third tier cargo space, second tier cargo space, and fourth tier cargo space, and then the portion of the empty first tier cargo space, fifth tier cargo space, and mixed storage cargo space is replenished when there are empty slots in the movable cargo space queuing locations.

In one possible implementation manner, the control server may further select a target movable carrier meeting the loading condition from the determined preferred movable carriers to perform the goods loading process. Specific:

the control server 11 is further configured to, after assigning the racking task to the workstation, i.e. after the racking demand for the goods to be racking on the goods-conveying device, schedule the at least one handling device to handle the at least one target movable carrier from the respective movable carrier queuing position to the at least one goods racking position, and schedule the at least one automatic racking device located at the workstation to place the goods to be racking located at the workstation onto the at least one target movable carrier, in case it is determined that the at least one target movable carrier satisfying the racking condition is present in the at least one preferred movable carrier according to the racking task.

The handling device 12 is configured to handle at least one target movable carrier from a respective movable carrier queuing position to at least one on-load rack position.

The automatic racking device 13 is configured to put goods to be racking at the workstation on at least one target movable carrier.

Above, meeting the loading condition may be for the goods to be loaded, where the target movable carrier has a target storage space for storing the goods to be loaded, and the target storage space may be an empty space or a hybrid storage space.

The control memory stores the position of each movable carrier queuing position and the position of each goods loading position, and after the target movable carrier is determined, the handling equipment can be scheduled to handle to the corresponding goods loading position from the corresponding movable carrier queuing position. And dispatching the automatic loading equipment, acquiring the goods to be loaded from the corresponding goods delivery positions, and placing the goods to be loaded on the target movable carriers of the corresponding goods loading positions.

For example, the empty movable carrier may satisfy any racking condition for a cargo to be racking. After allocation to the work station for the loading task, any empty mobile carrier can be screened directly from the preferred mobile carrier, and the scheduling handling device is used for handling the empty mobile carrier from the corresponding mobile queuing position to the goods loading position. Alternatively, the handling device may be configured to handle the empty mobile carriers closest to the load-on-shelf from the corresponding mobile queuing locations to the load-on-shelf according to the priority of the queuing locations.

In a possible embodiment, the control server 11 is further configured to, after assigning the racking task to the workstation, screen out at least one target movable carrier satisfying the racking condition from the carrier storage area based on the racking requirement information of the goods to be racking and the current empty carrier position information of the respective movable carrier, and schedule at least one handling device to handle the screened out at least one target movable carrier to at least one empty goods racking position located at the workstation, in case it is determined that there is no at least one target movable carrier satisfying the racking condition in the at least one preferred movable carrier according to the racking task.

The handling device 12 is configured to handle the selected at least one target mobile carrier to at least one empty cargo overhead at the workstation.

The control memory stores the position of each movable carrier in the carrier storage area and the position of each goods upper rack, after determining the target movable carrier in the carrier storage area, the control memory can dispatch the carrying equipment to carry the target movable carrier from the corresponding position of the carrier storage area to the corresponding goods upper rack position. And dispatching the automatic loading equipment, acquiring the goods to be loaded from the corresponding goods delivery positions, and placing the goods to be loaded on the target movable carriers of the corresponding goods loading positions.

In some embodiments, any one of the at least one workstation is provided with at least one egress location; the control server 11 is further configured to determine target racking requirement information of a target to-be-shelved cargo located at the at least one shipment level; scheduling at least one automatic racking device located at the workstation to place target goods to be racking on target storage locations in at least one target movable carrier based on the at least one target racking demand information; the target storage cargo space is a storage cargo space indicated by target on-shelf demand information.

Here, the case where the pop-up condition is satisfied includes: the empty cargo space existing in the target movable carrier is the cargo space indicated by the target on-shelf demand information, or the mixed storage space existing in the target movable carrier is the cargo space indicated by the target on-shelf demand information.

Illustratively, the target to-be-shelved cargo 181 is to-be-shelved cargo located at the shipment level 20 on the cargo conveyor 14 shown in FIG. 1. After the goods to be shelved are transported to the goods outlet position 20 by the goods transporting device, the control server receives the target shelving demand information of the goods to be shelved, then, according to the target shelving demand information, whether a target storage goods position meeting the shelving condition exists in the target movable carrier positioned at the goods shelves 15 can be judged, and if the target storage goods position meeting the shelving condition exists, the automatic shelving equipment can be scheduled to put the goods to be shelved positioned at the goods outlet position on the target storage goods position in the target movable carrier.

Here, if the target movable carriers of the plurality of cargo loading positions 15 simultaneously have target storage positions satisfying the loading conditions, it is sufficient to randomly determine one target storage position satisfying the loading conditions.

The target to-be-shelved demand information indicates that the target to-be-shelved goods are to be stored in the third-layer goods space, the target to-be-shelved goods cannot be stored in a mixed mode with other to-be-shelved goods, and if the third-layer goods space exists in the target movable carrier currently located in the movable carrier queuing position, the target movable carrier can be determined to meet the to-be-shelved goods loading condition; if the third layer cargo space is not empty in the target movable carrier currently located in the movable carrier queuing position, it can be determined that the target movable carrier does not meet the loading condition of the target cargo to be loaded.

And then, the target movable carrier with the goods to be put on the rack can be directly conveyed back to the carrier storage area. Or, whether the target movable carrier on which the goods to be put are placed still meets the shelving conditions of other goods to be put on or not can be judged, and if the target movable carrier is confirmed to be met, the target movable carrier can be carried to an empty movable carrier queuing position to wait for the next call.

Here, if there is no target storage space satisfying the loading condition among the target movable carriers of the loading position of the cargo, the target movable carriers of the loading position of the cargo may have the following processing manner:

in the mode 1, when no target storage cargo space exists in the target movable carriers of the cargo loading rack, and the target movable carriers of the cargo loading rack meet the loading conditions of other cargoes to be loaded, the dispatching and carrying device transfers the target movable carriers of the cargo loading rack to the empty movable carrier queuing position.

For example, when the target loading demand information indicates that the storage cargo space of the target cargo to be loaded is the third-layer cargo space, the third-layer cargo space of the target movable carrier positioned at the movable carrier loading queue is not empty, and the target cargo to be loaded cannot be stored in a mixed manner with other cargo to be loaded, it may be determined that the target storage cargo space does not exist in the target movable carrier of the cargo loading queue, and if it is further determined that the first-layer cargo space, the second-layer cargo space, the fourth-layer cargo space, and the fifth-layer cargo space exist in the target movable carrier of the cargo loading queue, it may be determined that the target movable carrier will meet the loading demands of other cargo to be loaded with a large probability, and therefore, the handling device may be scheduled to transfer the target movable carrier of the current cargo loading queue to the empty movable carrier queue.

In the case where the target loading demand information indicates that the storage cargo space of the target cargo to be loaded is a mixed storage cargo space mixed with the cargo D, the target movable carrier located at the cargo loading position does not have the mixed storage cargo space mixed with the cargo D, and it is determined that the target storage cargo space does not exist in the target movable carrier of the cargo loading position, however, since the control server determines that the target movable carrier having the mixed storage cargo space satisfies the loading condition of the cargo to be loaded in the process of screening the target movable carrier, the target movable carrier of the mixed storage cargo space satisfies the loading condition of the cargo to be loaded, and therefore, the handling device can be scheduled to transfer the target movable carrier having the mixed storage cargo space on the cargo loading position to the empty movable carrier queuing position, and waits for the loading demand of the cargo to be loaded C of the mixed storage cargo to be loaded.

In some embodiments, the control server 11 is further configured to invoke at least one handling device to transfer the preferred mobile carrier having a waiting period in the mobile carrier queuing position exceeding the preset period into the carrier storage area.

For example, as the empty target movable carrier continuously receives the goods to be shelved, the probability that the target movable carrier receives the target goods to be shelved again at the goods loading position will decrease, for example, if the target movable carrier only leaves the first layer of goods space or the fifth layer of goods space to be empty, the target movable carrier is continuously scheduled to be moved to the movable carrier queuing position by the handling device, the target movable carrier leaving the goods loading position to the movable carrier queuing position is a preferred movable carrier, if the waiting time period of the preferred movable carrier at the movable carrier queuing position exceeds the preset time period, at this time, the handling device may be scheduled to transfer the preferred movable carrier having the waiting time period exceeding the preset time period at the movable carrier queuing position into the carrier storage area.

For example, in the case that the control server does not receive the loading requirement of the target goods to be loaded for a long time, the handling device may be invoked to transfer the preferred movable carrier having the waiting time of the movable carrier queuing bit exceeding the preset time into the carrier storage area.

In the mode 2, under the condition that the target movable carrier of the goods loading position does not have a target storage goods position and the target movable carrier of the goods loading position does not meet the loading conditions of other goods to be loaded, the dispatching and carrying equipment transfers the target movable carrier of the goods loading position into the carrier storage area.

In an exemplary embodiment, when the target loading demand information indicates that the storage space of the target to-be-loaded cargo to be loaded is the first-layer space, and the first-layer space of the target movable carrier located at the loading space is not empty and the first-layer space of the non-empty space does not belong to the mixed storage space, it may be determined that the target storage space does not exist in the target movable carrier of the loading space, or it may be determined that the loading condition of other to-be-loaded cargo is not satisfied in the target movable carrier of the loading space, so that the handling device may be scheduled to transfer the target movable carrier of the current loading space into the carrier storage area.

After the dispatching and carrying equipment transfers the preferable movable carrier to the carrier storage area, a vacant position of the movable carrier queuing position appears, and at this time, the control server can call the movable carrier queuing position with the carrying equipment vacant again to supplement the target movable carrier. In a possible embodiment, the control server 11 is further configured to screen out at least one preferred mobile carrier from the carrier storage area and schedule at least one handling device to handle the at least one preferred mobile carrier to at least one empty mobile carrier queuing position at the workstation based on the number of mobile carrier queuing positions, the number of preferred mobile carriers on the mobile carrier queuing positions, the loading demand information of the goods to be loaded and the current empty carrier position information of the respective mobile carrier, if the number of preferred mobile carriers on the mobile carrier queuing positions is less than a preset threshold. It should be noted that, the specific value of the preset threshold may be defined according to an actual application scenario, and the embodiment of the disclosure is not specifically limited.

For example, in the case that the number of preferred movable carriers on the movable carrier queuing positions is less than the preset threshold, the number of preferred movable carriers subtracted from the number of movable carrier queuing positions is the number of preferred movable carriers to be supplemented, and then the supplementary preferred movable carriers are determined according to the above screening process based on the number of supplementary preferred movable carriers, the loading demand information of the goods to be loaded, and the current empty carrier information of each movable carrier. And scheduling the handling device to handle the at least one complementary, preferably mobile carrier to at least one empty mobile carrier queuing position at the workstation.

In the mode 3, when the target movable carrier of the goods-loading rack does not have the target storage rack and the target goods are stored in the target movable carrier of the goods-loading rack, the dispatching and carrying device transfers the target movable carrier of the goods-loading rack into the carrier storage area.

Here, the target cargo may include cargo to be picked, which is cargo to be picked out of the movable carrier. In the case where the control server receives a picking request of the target cargo stored on the target movable carrier, the dispatch handling device is transferred to the carrier storage area for the target movable carrier on which the cargo is placed to wait for the picking of the target cargo in the carrier storage area. It should be noted that, the target goods may also include goods to be delivered from a warehouse, or other goods to be transferred, and different categories may be set according to different application scenarios, which is not specifically limited in the embodiments of the present disclosure.

In some embodiments, the control server 11 is further configured to schedule the handling device to transfer the preferred movable carrier of the movable carrier queuing position into the carrier storage area in case the preferred movable carrier does not meet the racking condition of the goods to be racking.

Here, the case where the preferable movable carrier of the movable carrier queuing position does not satisfy the loading condition of the goods to be loaded may refer to a processing manner (for example, the foregoing manners 1 to 3) in which the target movable carrier does not have the target storage position satisfying the loading condition, and the repetition is not repeated herein.

In some embodiments, where the preferred mobile carrier with the mobile carrier queuing bit stores the target good, the handling device may also be scheduled to transfer the preferred mobile carrier with the target good stored to another area. Here, the other area may be a cargo delivery area or the like. Then, the handling device may be scheduled again to handle the preferred mobile carrier to the empty mobile carrier queuing position based on the loading demand information of each to-be-loaded cargo and the current empty carrier position information of each mobile carrier, or the preferred mobile carrier that has been calculated according to the priority order.

It should be noted that, the control server stores the position of each movable carrier in the carrier storage area and the position of the movable carrier queuing position, so the transporting device can be scheduled to transfer the preferred movable carrier to the empty movable carrier queuing position based on the position of the preferred movable carrier in the carrier storage area and the position of the movable carrier queuing position.

In addition, after the movable target carrier moves out of the upper cargo rack, the movable target carrier can be sequentially supplemented for the upper cargo rack according to the direction shown in fig. 1. An automatic racking device may provide a target movable carrier at least one cargo racking location with cargo to be racking.

Continuing the above process of screening the preferred mobile carriers, a detailed description is given below of screening at least one preferred mobile carrier from the carrier storage area:

in general, the movable carriers in the carrier storage area store goods, and the number of empty movable carriers is small or even none, so the number of empty movable carriers determined by the control server often cannot meet the requirement of loading all the goods to be loaded on the rack. In some embodiments, the control server 11 is further configured to determine the number of empty mobile carriers based on the current empty space information of each mobile carrier, and in case the number of empty mobile carriers is less than the number of mobile carrier queuing bits, screen out at least one preferred mobile carrier from the carrier storage area based on the racking demand information of the goods to be racking and the current empty space information of each mobile carrier; the number of non-empty movable carriers in the preferred movable carrier is determined based on the racking requirement information of the remaining racking goods of the racking goods other than the racking to empty movable carrier and the number of movable carrier queuing positions minus the number of empty movable carriers in the preferred movable carrier.

For example, whether the movable carrier is an empty movable carrier in the carrier storage area may be detected based on the position information of the empty carrier indicated by the empty carrier information, and the number of empty movable carriers may be determined based on the detection result. The control server stores the number of the queuing positions of the movable carriers, and then compares the number of the queuing positions of the movable carriers with the number of the empty movable carriers, and under the condition that the number of the empty movable carriers is smaller than the number of the queuing positions of the movable carriers, the empty movable carriers can meet the loading conditions of any goods to be loaded, so that all the empty movable carriers can be used as preferential movable carriers. And then, subtracting the number of the empty movable carriers in the preferred movable carriers from the number of the empty movable carriers except for the information of the loading demand of the remaining to-be-loaded cargos of the to-be-loaded movable carriers in the loading cargos, and the number of the empty movable carriers in the preferred movable carriers, and screening the remaining number of the preferred movable carriers from the non-empty movable carriers in the carrier storage area, wherein the remaining number is the number of the empty movable carriers subtracted by the number of the empty movable carriers in the preferred movable carriers.

For example, taking an example of having 10 movable carriers queued, only two empty movable carriers among the movable carriers in the carrier storage area can be detected based on the position information of the empty carrier indicated by the empty carrier information. The empty mobile carrier may be considered as the preferred mobile carrier and the remaining 8 mobile carriers may be queued for queuing to park the non-empty mobile carriers. The non-empty movable carriers include movable carriers without empty spaces and movable carriers with empty spaces, and based on the information of the loading requirements of the respective cargoes to be loaded, if the information of the loading requirements indicates that no cargoes to be loaded which are required to be mixed and stored in the cargoes to be loaded, the preferred movable carriers can be directly selected from the movable carriers with empty spaces, for example, 50% of cargoes to be stored in the third layer of cargoes, 20% of cargoes to be stored in the second layer of cargoes, 20% of cargoes to be stored in the fourth layer of cargoes, and 5% of cargoes to be stored in the first layer of cargoes and the fifth layer of cargoes respectively are determined. The movable carriers with empty cargo space of 4 third layers can be selected as the preferable movable carriers, the movable carriers with empty cargo space of 2 second layers can be selected as the preferable movable carriers, and the movable carriers with empty cargo space of 2 fourth layers can be selected as the preferable movable carriers. Because the empty movable carriers can meet the loading conditions of all cargoes to be loaded, the preferential movable carriers matched with the cargoes to be loaded in the process of dispatching and conveying equipment in the follow-up process can be conveyed, and the preferential movable carriers which can meet the loading conditions in a high probability are preferentially conveyed in the process of dispatching and conveying equipment in the first wheel, namely, the empty movable carriers, the movable carriers with empty third-layer cargoes in the non-empty movable carriers, the movable carriers with empty second-layer cargoes and the movable carriers with empty fourth-layer cargoes.

If the loading demand information indicates that the to-be-loaded cargoes needing to be mixed and stored exist in the to-be-loaded cargoes, the type of the cargoes mixed and stored with the to-be-loaded cargoes needs to be determined, the movable carrier where the cargoes are located is determined, and the movable carrier where the cargoes are located is used as the optimal movable carrier. In some embodiments, the control server 11 is configured to determine the number of empty mobile carriers based on the current empty space information of each mobile carrier, and in case the number of empty mobile carriers is less than the number of mobile carrier queuing bits, take the empty mobile carrier as the preferred mobile carrier; if the shelving demand information indicates that goods to be shelved are in the goods to be shelved, determining a preferable movable carrier of a mixed storage goods position based on the goods class of the goods to be shelved; the remaining number of preferred mobile carriers is determined based on the number of mobile carriers queuing positions, the number of empty mobile carriers and the number of preferred mobile carriers of the mixed storage cargo space, and the remaining number of preferred mobile carriers is selected from the mobile carriers with empty cargo spaces, and the specific selection process may refer to the selection process of the above embodiment, and the repetition of the repetition is omitted.

In a possible implementation manner, in the case that the movable carriers in the carrier storage area only store a small amount of goods, a situation that the number of empty movable carriers is far more than the number of queuing positions of the movable carriers will occur, and because the empty movable carriers can meet the loading conditions of the goods to be loaded, the control server 11 is further configured to determine the number of empty movable carriers based on the current empty carrier position information of each movable carrier, and in the case that the number of empty movable carriers is greater than or equal to the number of queuing positions of the movable carriers, select at least one preferred movable carrier from the empty movable carriers based on the positions of each empty movable carrier and the loading requirement information of the goods to be loaded; wherein the number of the selected preferable movable carriers is smaller than or equal to the number of the queuing positions of the movable carriers. Here, the screening rule may be to screen the empty mobile carriers closest to the queuing position of the mobile carriers based on the positions of the respective empty mobile carriers. Here, the positions of the respective empty movable vehicles are stored in the control server.

Referring to fig. 3, which is a schematic flow chart of loading and storing goods to be loaded, specifically, a control server is used to schedule a handling device and an automatic loading device to complete loading and storing processes of goods to be loaded, including:

S301, analyzing the loading demand information of cargoes to be loaded and the current empty space information of each movable carrier, and calculating the optimal movable carrier;

s305, judging whether the target movable carrier on the goods loading position stores the target goods or not; if yes, then S310 is performed; if not, then S306 is performed;

s306, judging whether a target movable carrier on the goods loading position meets loading conditions of other goods to be loaded; if yes, then execution S307; if not, then S310 is performed;

s307, the dispatching and carrying equipment carries the target movable carrier on the goods to the empty movable carrier queuing position, and then the S303 is circularly executed.

S308, determining the waiting time of the preferable movable carrier in the movable carrier queuing position.

S309, judging whether the waiting time of the preferable movable carrier at the movable carrier queuing position exceeds a preset time; if yes, then S310 is performed; if not, S309 is performed in a loop.

S310, dispatching the handling equipment to handle the preferably movable carrier into a carrier storage area;

s311, judging whether the number of the preferable movable carriers on the movable carrier queuing position is less than a preset threshold value; if yes, then S312 is performed; if not, the process loops to S311;

s312, calculating complementary preferred movable carriers based on the number of the movable carrier queuing positions, the number of preferred movable carriers on the movable carrier queuing positions, the information of the loading demand of the cargoes to be loaded and the current empty carrier position information of each movable carrier, and then executing step S302;

s313, dispatching the automatic racking equipment to put the target goods to be shelved on the target storage goods position in the target movable carrier, and ending the flow.

According to the process of loading and storing the goods to be loaded, the control server is utilized to pre-record the loading demand information of each goods to be loaded, the transport equipment is firstly scheduled to transport at least one preferable movable carrier to the empty movable carrier queuing position, then under the condition that the control server obtains the loading demand of the goods to be loaded, the control server is utilized to receive the goods to be loaded on one preferable movable carrier in the movable carrier queuing position, and the distance from the movable carrier queuing position to the automatic loading equipment is far smaller than the distance from the movable carrier in the carrier storage area to the automatic loading equipment, so that after the control server obtains the loading demand of the goods to be loaded, the preferable movable carrier of the goods to be loaded on the storage target can be quickly matched from the movable carrier queuing position, the time of the automatic loading equipment waiting for the preferable movable carrier is greatly shortened, and the working efficiency of the automatic loading equipment is improved.
